Nautilus doesn't show the icons on the correct screen when switching between a dualhead and single head configuration with xinerama.

Steps to reproduce:

Configure you xorg.conf to support the following layouts:

Layout "single"
   Screen "Primary" # primary screen used in single display

Layout "dual"
   Screen "Primary" # primary screen used in single display
   Screen "Secondary" LeftOf "Primary # Secondary screen 

Expected Result:

In the dual layout, the primary screen should have the look of a normal primary screen.

Actual Result:

The icons on my desktop are all moved to the left screen while the panel stays on the primary screen. Since my external screen is smaller than my internal (Laptop), I have some icons (normally on the left of my primary) now on the right border of my primary, which looks strange.

Reproducible:

always.

This should be fixable since gnome-panel can do this by itself.
